EXPLANATION OF THE PLATES. 



The majority of the figures in the following Plates were made with the 

 assistance of the Camera Lucida, and the same instrument will be em- 

 ployed in the delineation of all future figures wherever practicable. 



PLATE XLV. 



Fig. 1. Filaments of the Great Sympathetic magnified 670 

 diameters. 



Fig. 2. Cells of the grey matter of the Cerebellum, outer 

 stratum. 



Fig. 3. Ditto, inner stratum. 



Fig. 4. Caudate ganglionary cells from the grey matter of the 

 Spinal Cord, Medulla Oblongata, and Cerebellum, 

 magnified 350 diameters. Those from the first 

 locality are distinguished from the rest by their 

 larger size ; those from the second situation by their 

 smallness and elongated form, and the cells from 

 the cerebellum by their intermediate size and flask 

 shape. 



Fig. 5. Caudate ganglionary cells from the Locus Niger of 

 the Cms Cerebelli, 350 diameters. 



Fig. 6. Minute caudate cells from the Hippocampus major, 

 350 diameters. 



Fig. 7. Ditto, from the Locus Niger of Crus Cerebri, 350 

 diameters.
